About this map

Pentagon Mtn stands as the central landmark in this high-altitude section of the Lewis and Clark Range, where the continental divide meets the boundaries of two major national forests. This 2017 survey details the complex topography at the junction of Flathead National Forest and Lewis & Clark National Forest, specifically where Flathead County and Lewis and Clark County meet. The map documents a primitive network of high-country routes, most notably the crossing at Switchback Pass south of Kevan Mtn.

Drainage systems define the movement of water from the peaks, with Strawberry Cr and Clack Cr flowing through the northern reaches, while the S Fork Open Cr carves through the southern terrain near Moonlight Peak. The map provides a clear look at the literal and physical intersections of state-managed lands, showing the surveyor's lines for T26N and T25N across summits like Bow Mtn and Signal Mtn.
